Downscale lunch for Reese

Reese Witherspoon isn't all about those fancy dinners on Rittenhouse Square.

She and kids joined the Saturday lunch rush at the Ruby's Diner by Suburban Square in Ardmore, near her Main Line rental.

Sometimes, a burger amid screaming young'uns and a blaring jukebox is all you need on a muggy Saturday.

Witherspoon and her castmates on the untitled James L. Brooks comedy reported to work Saturday night for a rare weekend shoot.
